FORCE- PUMP.

SEECIFICATION forming part of Letters Patent N o. 668,542, dated February 19, 1901.

Application filed July 23. 1900. Serial No. 24.549. LNo model.)

T0 all whom, t Wray concern-f Be itknown thatLWAsHINGToN I. PHIFER, a citizen of the United States, residing at California, in the county'of Moniteau and State of Missouri, have invented a new and useful Force-Pump, of which the following is a specification.

My invention relates to pumps, and more particularly to that class of force-pumps which are adapted to throw aconstant stream of wa` ter; and it consists of the improved construction and novel arrangement of parts of such a pump, as Wi-ll be hereinafter more fully set forth.

In the accompanying drawings, in which the same reference-numerals indicate corresponding parts in each of the views in which they occur, Figure 1 is a perspective View of my pump, the lower portion shown in longitudinal-section. Fig. 2 is a Vertical sectional view of the head or upper portion of the pump. Fig. 3 is an elevation of the stand or head, and Fig. 4 is an enlarged sectional detailview of the lower portion of the pump.

Referring more particularly to the drawings, 1 indicates the head or stand of my improved pump, which is preferably substantially triangular or A shaped, provided with a circular brace or stiffener 2. A shaft 3 is journaled in a suitable bearing at the top of the head and is provided with a crank at each end, one of the cranks, 4L, forming a handle for operating the pump and the other crank, 5, being integral therewith and connected with the piston-rod 6 by means of the pitman 7. The piston-rod 6 extends down through the pipe 8 or water-outlet and is connected at its lower end with a cylinder 9, which is adapted to be reciprocated within a cylinder 10. A piece of hollow tubing 11 is rigidly secured to the lower end of the pipe 8 and extends down intO the cylinder 9 and has its lower end expanded, as shown at 12, and provided with suitable packing 13 to engage with the inner surface of the cylinder and prevent the passage of water from the cylinder except up through the tubing and the pipe and out at the spout or discharge-orifice 14, which is located at one sideof the head of the pump.

The spout com prises two parts, one of which is formed integral with the base and is provided with a stuffing-box 15, and the other part, 16, is swiveledto the top of the stationary part and provided with an air-chamber 16. The lower end of the stationary piece is curved from the stufling-box, which is located directly below the crank 5, to a point at one side, where it can stand vertically and have its upper end at the side of the head. This will permit of the swiveled portion being turned almost one-third of a revolution,there by making a very desirable construction.

Secured to the top of the tubing or the bottom of the pipe where it is joined thereto is a suitable cross-head 17, which may be circular if desired. Bolts 18 extend from the crosshead down to the upper end of the cylinder 10 and rigidly hold the cylinder in its proper position for the recprocation therein of the inner cylinder 9. The lower end of the cylinder 10 is provided with a suitableinwardlyopening valveI 19, through which water passes tothe interior of the cylinder when the inner cylinder is moved upward. The lower end of the inner cylinder is also provided with an inwardly-opening valve 20, through which the water within the cylinder l0 passes to the interior of the cylinder 9 when the cylinder 9 is moved downward. The exterior of the bottom of the inner cylinder is provided with suitable packing for engaging with the interior of the cylinder 10 and preventing the passage of the Water from the ou ter cylinder except through the valve into the inner cylinder. The upper end of each of said cylinders is open and the capacity of the outer cylinder is substantially double that of the inner cylinder, so that after the outer cylinder has been illed by the upward movement of the inner cylinder the downward movement of the inner cylinder will cause the water to pass into the inner cylinder and completely fill the same as it moves downward; but as the capacity of the inner cylinder is less than the outer cylinder the downward movement of the inner cylinder will force a greater quantity of water thercinto than it can contain, which will canse the excess to be forced up through the dischargepipe and delivered from the spout while the cylinder is making its downward movement. As soon as the inner cylinder starts on the upstroke the water contained therein will be forced up through the discharge-pipe and out at the IOO spout, thereby causing a constant stream of water under pressure to be delivered from the spout, the air in the air-chamber continuing the stream during the small interval in which the inner cylinder is changing its reciprocation.

By constructing my improved pump as above described it will be seen that a good substantial support is secured for the upper end or discharge-spout and an easy and positive movement secured for the piston-rod by the arrangement of the crank-shaft at the top of the head or stand for the pump. By forming the two cylinders open at their upper ends the pump mechanism can be cheaply manufactured and can be quickly and easily assembled or taken to pieces for the purpose of repairing or cleansing. rlhe pipe can be made of suflicient length to reach the water in the deepest well and should be made of sufficient size to permit of the easy passage of the water from the cylinders to the spout.

Having thus fully described my invention, what claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a pump, the combination, with a stand, of a pipe, the upper end of which is provided with a spout and the lower end with a piece of tubing, the lower end of said tubing being expanded, a cross-head secured at the union of the pipe and the tubing, rods depending from the cross-head, an open-top cylinder secured to the lower ends of said rods, the lower end of said cylinder being provided with inwardly-opening valves, a rod within the pipe, an open-top cylinder secured to the lower end of said rod, the bottom of which engages with the interior of the outer cylinder and is provided with inwardlyopening valves, said cylinder engaging with the Banged portion of the tubing upon its interior and being of less capacity than the outer cylinder, and means at the top of the stand for reciprocating said rod, substantially as described.

2. In a pump, the combination of a plate having a support raised from its upper surface, the upper end of which is formed with a transversely-extending bearing, said plate having also a spout raised therefrom and communicating with an outlet formed in the plate, which outlet is disposed to one side of the spout, and with which the spout communicates by a laterally-curved passage, a pipe arranged on the under side of `said plate and in line with the outlet thereof, said laterallycurved passage of the spout having its upper wall perforated in line with the pipe, a stuifing-hox arranged at the upper end of said perforation, a piston-rod movable in said pipe and ext-ending therethrough and th rough the perforation and stuling box, a shaft arranged in the bearing of the support and having a crank-handle on one end and a crank-arm on the other end, a connectingrod pivotally connecting said crank-arm and piston-rod, a casing arranged at the lower end of said pipe and provided with inwardlyopening valves, and a cylindrical piston movable in said casing and carried by the lower end of the piston-rod, and provided with inwardly-opening valves, substantially as described.
